A chair lift takes skiers to the top of a mountain that is 320 m high. The average mass of skiers complete with equipment is 85 kg . The chair lift can deliver three skiers to the top of the mountain every 36 s
Determine the power required to carry out this task
If friction increases the power by 25% what power must the motor running the lift be able to deliver
massrate= 85/36 kg/second
power= force*distance/time= force/time *distance
I am not certain what the last question states.
